Ok so I've searched on here for a while and I've found the answer to my question but its not a straight forward answer. I know this topic has been covered a lot, I just want to make sure I'm getting the right stuff. I'm replacing my old broken diff with an MFactory diff and I need to know which MTF to run. I know there's a lot of fluids out there but some require an additive when running a limited slip or they require a GL-4 or GL-5 fluid. Can I use something like the mobile 1 syn. 75w90 gear oil?
 
Why not ask the manufacturer? I am sure they will point you in the right direction. Especially since it is their area of expertise and you just spent $750 with their company.
 
So they day to use torco transmission fluid. Im going to research this more first tho
 
The LSD does not require additive, the lubricants in GL-5 gear oil are good enough for the Diff and safe for the synchros in the trans. I believe even the GL4 is good enough as the synchros are not bronze.
